IPC: B62D25/18
Filed: 1924-03-10
Abstract: 229,867. Lenoir, C. March 10, 1924. No Patent granted (Sealing fee not paid). Lateral-splash guards. - A splash guard for motor vehicles comprises a vertical portion 1 and an oblique portion 2 held on a cross-beam fixed to a connecting-rod 7 which is mounted by a boss 16 upon a support on the wheel axle comprising two rings 18, 20 having limited rotary movement in opposite directions and connected by a torsion spring 19. The ring 18 has internal and external recesses 21, 25, Fig. 6, in which are lodged respectively, a key 23, fixed on the stub shart 17, and a key 28 in the boss 16. The ring 20 is similarly constructed. The stub shaft 17 is hollowed out for a rear wheel to receive a ball bearing and is connected to the footboard &c. by an adjustable rod. A wood fibre bar 6 contacts the wheel rim and thus lifts the guard when it encounters an obstacle. A cross-bar 3 is removably attached by bolts to the connecting-rod 7. The connecting-rod may be telescopic and contain an adjustable spring. In the modification shown in Fig. 9 two levers 37, 38 arepivoted on the stub shaft 17 a.nd connected by a. spring 39. A stop 41 on 'the connecting-rod 7 projecting between the levers can move either of the levers while the other is held by a stop 40 on the stub shaft.

Patent GB-834198-A (GB)
Title: Improvements in or relating to the production of glass
Inventor: SMITH ARTHUR JAMES
IPC: C03C3/32
Filed: 1956-03-05
Abstract: To produce relatively large pieces of arsenic trisulphide glass, the crucible in which it is prepared is suddenly chilled during the slow cooling of the melt when the latter has become rigid, to cause separation without fracture.  About 5 kg. of liquid arsenic trisulphide is collected in a conical silica crucible at 570 DEG  to 700 DEG  C.  The crucible is then heated and contents stirred for 20 minutes at 625 DEG  C. to homogenize the melt and thereafter the temperature is maintained at 300 DEG  C. for seven hours.  The temperature is then slowly reduced to 220 DEG  C. and maintained for 4 1/2 hours after which the crucible is plunged in water at room temperature for twenty seconds, causing the glass to separate from it.  The crucible and contents are then returned to the furnace and maintained at 220 DEG  C. for one hour before slow cooling.  This glass is transparent to infra-red light and contains 58.4% arsenic and 41.6% sulphur but reference is made to the addition of modifying agents such as arsenic, sulphur, selenium and tellurium.

Abstract: 1,040,132. Pneumatic single stroke apparatus. GIRLING Ltd. Feb. 13, 1964 [Feb. 21, 1963], No. 6973/63. Heading F1P. [Also in Divisions F2 and G3] A servomotor suitable for operation of the master cylinder of a vehicle hydraulic braking system comprises a housing 10 with a fixed partition 26 and a movable assembly consisting of a diaphragm 25 backed by a piston 24 integral with a boss 64 and a diaphragm 27 backed by a resilient sheet metal disc 28 itself backed by a mushroom head 45 of a sleeve 43 secured to the boss 64 and slidable within an outer sleeve 44. Vacuum applied through a connection 42 to a chamber 20 has access through passages 30 in the partition 26 to a chamber 22 and, with valves 52, 67 in the positions shown, can pass from the chamber 22 through passages 63, 69, 70, 71 to a chamber 23 and thence through passages 31 in the partition 26 to a chamber 21. When an actuating rod 51 is moved inwardly it seats the valve 52 on the valve 67 to cut off the -vacuum connection with thechambers 23, 21 and thereafter lifts the valve 67 from a seat 73 to connect the chambers 23, 21 to atmosphere through passages 74, 75, 61 and an air filter 62. The movable diaphragm assembly then moves leftwardly until the seat 73 re-engages the valve 67. Should the servomotor fail to respond, continued inwardmovement of the rod 51 brings a member 56 into engagement with the end of the sleeve 43 to cause direct actuation of the diaphragm assembly. The valve 67 comprises a rubber diaphragm 68 backed by a rigid plate 72 and clamped at its periphery between the parts 64, 43. The thickened inner portion 47 of the diaphragm 27 is held in a groove 46 in the sleeve 43 by a U-shaped member 48 of spring steel which passes through holes in the outer sleeve 44 permitting relative movement between the sleeves 43, 44. The thickened inner portion 38 of the diaphragm 25 is secured in an annular recess 39 by a selflocking ring 40 with resilient teeth. The housing 10 is constructed as described in Specification 1,040,133.

Abstract: 783,686. Synchronous machines. KELLMA AKTIEBOLAG. March 7, 1956 [March 19, 1955], No. 7161/56. Class 35. The rotating field member 3 of a synchronous machine is excited by direct connection to an exciter 4 having a rectifying commutator and fed with polyphase current from the stator windings 2 of the main machine. The stator of the exciter has a polyphase winding 6 carrying the load current of the main machine, and a second winding 5 energized from tapping points on the main machine, so that compounding is achieved. The winding 5 is connected to a stationary commutator 7 engaged by brushes 8 connected to and revolving with the main rotor 3. Adjustment of excitation may be made by rheostats 13, 14, by axial displacement of the core carrying the winding 6, or by rotation of the whole stator and commutator. Powerfactor correction is made by relative rotation of the stator windings. In a modification the winding 5 is replaced by a three-phase resistance divider comprising resistances connected to the commutator segments or simply a resistive ring. The A.C. and D.C. parts may be interchanged by providing three-phase brushes.

[Class 87 (ii)] A resilient product comprises a, casing of rubber or rubber-impregnated sheet material hot-moulded on to a felt body and completely encasing the latter, the rubber being of non- uniform thickness thereby giving the product an external contour different from tha,t of the felt body and obviating machining of the felt to the shape of the finished product. Prior to insertion in the mould, pieces of solid rubber may be secured to the felt by rubber solution or other adhesive ; alternatively the felt and rubber unit may be built up in the mould, or the felt may be supported in the mould and rubber mix injected therein. The non-uniformity in thickness of the rubber may be obtained by applying an increased thickness at the appropriate place, e.g. where a rib is to be formed, the mould cavity being shaped to form the rib. The felt may previously be impregnated with rubber.
